To all whom it may crmcern:

',dlii11e constructed on the MACHINE FOR GUI LING AND WEAVING. WIRE.

Be it known that l, 'WILBEI: J. PINE, a citizen of the United States, residing at Oshkosh, in the count 7 of Winnebago and State of Vv'is'consin, have invented certain new and useful Improvements in Machines for'Coiling and eaving ire Into a Fabric, of:

whicl'i the following is a specification.

My invention relates to machines for coiling and weaving wire into a fabric, such as are employed, for instance, in the manufactureof Wire mattresses, although, as will beunderstood, the fabric produced by my machine may be pur oses.

T 1e object of my invention is to produce a novel, efficient and reliable machine of this character operating in an automatic manner, beginning with the taking of the wire from the reel and ending with the production of the complete wire fabric. The machine is, more over, provided with various adjustments whereby the length of the fabric may be regulated and whereby the diameter and pitch of coil may be adjusted as required for different characters of fabric and also for different styles or types of fabric of the same character or class. Moreover, the construction of my mechanism is such that a single fabric may be produced or by duplicating the number of trains .or gangs of such mechanism 0 er'ated from'a common source, the macl fine may be enabled to produce any number of fabrics at a single operation. In the resent instance, the particular machine fierein shown constructed, to simultaneously weave three separate and independent fabrics, but it will be understood that a 1na v same'general principlcs may be enabled to weave oneytwo, or any other number of fabrics atthe same time; according to the number pftrains or gangs of coiling and Weaving devicesiin such machine.

embodies and my invention contemplates novel and efficient n1ccl1- anism'for causing the weaving ,at any. particular' or predetermined location and; in any number, of extra wires or so called col-ids for strengthening purposes, such cords being'run longitudinally of the fabric at intervals-im ternlediate the widththereof and also'at-the sides of the'fabric' to form borders therefor; My cording or pattern mechanism, which Specification of Letters Patent.

5 thus determines the particular pattern of the fabric, is arrangedto meet all requirements as to the particular style or pattern of fabric as respects the cords, inasmuch as it is capable of following any pattern which may be I desired, the operation of the machine in respect to the running of the cords being entirely automatic after the desired pattern is supplied thereto. l

Furthermore, my machine embodies many other novel and advantageous features of construction and means of adjustmentfor other purposes, as well as means for automatically controlling-and stopping the ma chine in case the wire should be knotted as it comes from the reel, or should become snarledin-the machine. 7

Referring more particularly to Figs. 1, 2 and 3, the machine is provided with a main frame 1 of suitable size and dimensions for the urpose of: supporting the working parts of "t e machine. For convenience, I will hereinafter refer to the left hand end of the machine shown in Figs. 1, 2 and 3, where the coilers are located as the forward part, and the other end as the rearward part of the machine. 'As shown more particularly in Figs. 1, 4 and 6, the working parts of the machine,

'including the coilers and feed rolls, are mounted in anoscfllatmg frame or head arranged to reciprocate in a horizontal plane for apurnose hereinafter made apparent. As seen 111 Fig. 16 the parallel sides of thisoscil- Fig. 25 a sectional planon line the, spriu gs.

lating frame are arranged to slide in the outer sides'of the main frame any suitable I manner and such head is arranged to be positively operated. by operating connections hereinafter described.

The feed rollers are two in number and arranged to feed the wirefrorn the reels to the coilers in advance thereof. The upper feed roll comprises a shaft 3 journaled at its endsin bearings which may be adjustable in suitable manner in the sides of the oscillating head. This shaft which is driven by a train of gears hereinafter referred to, is surrounded by a series of sleeves 4 secured thereto and to which. are applied the inner rings 3 separatedby the distance sleeves 4 and collars 4., Fig. 14. On the rings 3 are ressed the hardened rings 5 which engage t e wire and which, in connection with similar rings on the lower feed roll, feed the wire to the coilers.

As -shown in Figs. 5 to 8 and 13, the lower feed roll comprisesa shaft 6, whose ends are journaled in. bearings vertically adjustable 1n suitable manner in the ends of the ad justable head. This shaft is surrounded by a series of pressure rings or collars 7, each having a yielding connectionwith the shaft6 through the medium of a coiled spring 8, the inner end of which is secured to the shaft 6 and the outer end to the inner surface of its collar, by the keys 9, respectively, Figs. 5 and 6. These pressure rings may be spaced in the same manner as-those of the upper feed roll.

Inasmuch as the coiled wire fabrics are I usually made from a pair of wires run practi cally as a single strand, the pressure rin s 7 ofthe lower feed roll and the correspon ing rings 5 of the upper feed'roll are arranged in corresponding to the coilers, so as to eed the iairs of wire from the reels to the coilers. n the present instance, the ma chine is provided with three gan s of mechanism arranged to simultaneously coil and weave three separate fabrics and consequently the feed rolls are each provided with three pairs of pressure rings or collars for feeding the six wires which are required for weaving the three separate fabrics, as clearly indicated in Fig. 13.

As above described, the Jressure rings or collars of thelower feed roll are not directly secured to or actuated by its shaft, but only through the yielding connection afforded by Moreover, the arrangement is such that no pressure exerted by the ressure rings or collars of the lower feed r'ol exthese collars resume their concentric relationship with their shaft, no pressure is exerted upon the wire and no feeding thereof takes place. This applying and relieving of ressure is intermittent and automatic an the .wire feed is correspondingly intermittent.

. i For the purpose of moving the pressure collars of the lower feed roll eccentric of their shaft for the purposes above stated, I provide suitable mechanism cooperating with each pair of pressure collars, such mechanism being arranged to be operated automaticallyat the proper time when it is desired to -have the wire fed into the machine. As shown more particularly in Figs. 1, 5 and 13, each of such mechanisms comprises a pair of ,y'o'kes or cradles having on opposite sides pairs of rollers 11 arranged to cooperate .withthe corresponding pair of res'sure collars 7. The cradles are provirlhd with depending'stems 12, whose lowerends pass 7 through a bracket 13 and bear upon the upper face of .a bar 14 which in turn is fulcrumed at its central point upona spring pressed pin. 15, Figs. 5 and 13. This pin is arranger to slide in the bore of an angular block .6, which is received by an adjustable bracket or plate-17. The block 16 is drilled fromv its top part way of its length and tapped as toits lower end so as to receive the z screw-threaded ad'usting screw. As indicated in Fig. 13, a slot is cut in one side of the block 16 so as to expose the head of the ad justing screw 18, which head is provided with holes to receive an instrument for the purpose of adjusting the screw and thereby -cau'sing the springlQ interposed between it land the pin 15 toexert more or less'tension.

1 -,The lower end .of'each block 16 is proyid'edwith a roller-20 arranged in the path of movementof a cam 21 which is mounted fupon a bar 22. This bar is reciprocated mautomaticallyby the machine and at the .;Er per time by the operating connections ereinafter described. 1 When the parts are fat the relative positions indicated in Fig. 13,

. the'blocks 16 are projected to their lower 'I'n'it of movement and are resting upon the pper edge of the bar'22, but when such bar .i'einoved to theright, Figs. 1 and 13, the

movement is communicated through hessjfqringsL-IQ; pins 15 and rollers 11 to the I fpie ssurelc'ollars of the lower feed roll, which collarsare thereby forced eccentric of their shaffl withuthe result th'atpressure is applied .66 "tofthe wire'and the -latter caused to be fed intoftheikmachine. As. shownin-Figs. 1. 5

- Candid, eacheain 2,1 is arranged tobe in-de-i pendefntly adjustable by sliding longitudinally of'lts' bar 22 so that. atthe will oi the so, peijator'any one orinore ofthe sets f presepollars-Inay be put. under tension to feed heyire' when it is desired to temp rarily tputhe feed rolls by hand in case an wire ould become snarled in the coilers oifltv'eavwaxing fdevices.-.1 To this end each cam 21;;is arranged to slide longitudinally upon its bar and is provided on its lower edge with rack teeth arranged to be engaged by a pinion 23 j ournaled on the outer side of the bar 22 and operated by the handle 24. By turning the handle in one direction or the other, the cam 21 is correspondingly reciprocated. By preference, each cam is provided with an adjustable stop which, as shown in Fig. 13, comprises an adjusting screw 25 screwing through a projection 26 on the bar 22 and arranged in the path of movement of its cam 21. v p

Inasmuch as it is found in practice that the wire froinonc reel isapt to run faster than the wire fro n'its companion reel, notwithstanding the same amount of pressure applied by the feed rol.ls,-it becomes necessary' to provide for a greater pressure upon one wire than upon its col'npanion wire so as toobtain a uniform feed. I accomplish this result by making each bracket 17:, which carries the block 16, adjustable laterally seas. to change or shift the position of the fulcru npf the bar 14 laterally with respect to the lower ends of the stems of the cradles. Ordinarily, that is when the same pressure is to be applied toboth pressure collars or thesame pair, the stems of thecradles corresponding thereto are positioned at equaldis'tances-on either-side of the vertical'lineof the fulcrum of the bar 14, as indicated in. Fig, 13, but when it is desired to apply the pressure unevenly to these pressure collars, the bracket 17 is shifted laterally inone direction or the other, according to whichever pressure 001- lar requires the greater pressure. It Wlll be seen that by shifting the fulcrum the relat onship of the stems of the cradles with relatlon thereto will be disturbed and the presshown in Figs. 1,2, 3 and 4, the motion is transmitted from the driving pulley 30, clutch 31 of any suitable. constructiomto a driving shaft 32. This driving shaft is pro vided with a worm 33 and also atits inner end with a inion 34, which meshes with a gear-35. T is gear meshes with a pinion 36 upon the eXtended-shaftfi of the lower feed roll, which shaft is also provided, with a pinion .37, in turn meshing with a pinion 38, se-

cured to the shaft 3 of the upperfeed roll.

The pinion 36 is feathered on, its shaftfi 50- lot sure consequently transmitted unevenly the case mav be.

cam 41 of A5, to which the arm 42 is secured.

' provide a locking that it may be moved longitudinally there of, out of mesh with the gear 35, so that the shaft 6 may be operated by hand whenever desired, independently of the remainder of the mechanism.

Referring to the operating connections for the reciprocating bar .32 the same comprises a worm gear 39 meshing with the worm 33 and secured to a main driving shaft 40. extending longitudinally of the machine, Figs. 1, 2 and-3. This shaft is provided with a eculiar construct-ion, asherein after descrl ed, and the same is adapted, through themedium of therockerarin 42 and its, cain roller 43 to rock the depending arm 44 secured to its upper end to the rock sl irtjft 1e lower end of this depending arm 44 is opera tively connectedwith the reciprocating bar 22, with the result that upon the rotation of the cam 41 the arm 44 is rocked laterally and the bar 22 correspondingly reciprocated. As stated, the cam 41 is of peculiar construction, inasmuch as it provides for an adjustment of the relative length of the period during which the bar 22- is in one position or the other. To this end,t-he cam-way is made adjustable byforming the inner wall of the cam wayas a ring 46, which ring is adjustable u on the hub 47 of the cam; To hold the an justable ring in itsaliiierent positions I screw 47 arranged to ena e one of a series of screw-threaded holes. l Vlien the adjustable ring 46 is moved in one direction or the other, the high and low sides thereof are adjusted relatively to the high and low sides or summits of the outer cam roll, with the result that the length of the two dwells in the cam are lengthened or shortened,. as the case may be and the length. 01 time required during which the reciprocating bar 22 remains in one position or the other is correspondingly lengthened or shortened, as

In front oi the feed rolls are located'guides arranged in pairs and through which the Wires are caused to pass before reaching the feed rolls. As shown in Figs. 1, 5, 9 and 10, these guides comprise two portions 50 and 51, the lower portion 50 being a rectangular block secured upon the bracket 52 on the oscillating head and grooved longitudinally to receive a corresponding de endin rib or fin 53, on the upper member w liCll is likewise in the form of the-rectangular block or plate. The upper block 51 sim )ly presses u on the wire as itmesses through the channe of the lower bloc 50., with its own gravity, but the same is prevented from being displaced in suitable manner, as by means of a cross arm i 54 held-in position above the bracket and across the-pair of the blocks 51 by a post 55 extending lnto the bracketfil.

' .After the wire passes through the guides the same is delivered to the feed rolls and is receive the shells. locked in place by means of the set screw 60' then passed through the coilers now to be described. These coilers are in thepresent instance, (in the three-gang machinenow being described) six-in number, arranged in three pairs, the description of one coiler applying to all. As shown in Figs. 5 and 11, each coiler is substantially a cylinder 56, which is feed rolls and to receive the wire as it is fed therefrom, To hold the coilers' and their shells in place, I provide each coiler and shell with a pin 58 extending throughthe shell and anchored into the block 59, which is rovided with transverse grooves arran cc to The coilers and she lsare passing through the transverse bar 61 rising from the block 59 and pressing at its lower end against said shell.

For the purpose of adjusting the coils of thewire to the proper and desired pitch I arrange behind each coiler a tensioner comprising a cylinder 62, Figs. 5 and 12, also arranged within its own incasing shell 63'and provided with a spiral groove 64. This groove is enlarged at its forward end and arranged to register with the groove at the rearward end of the coiler but by the rotary adjustment of the tensioner the continuity ofthe spiral 321th of the wire is altered as it leaves the coiler and the pitch of such wire is thereupon determined, inasmuch as the wire is put under a tension and the pitch is lengthened or shortened according to the particular adjustment of the tension. To hold the tensioner in position and to errnit of its adjustment to a nicety I provie e each of the incasing shells 63' which are secured to their tensioncr 62 b r a pin (35 with a worm gear 66, Fig. 15. dependent adjusting mechanism and to this E2161 tensioner is provided with in end each worm gear meshes with a wdrm 67 journaled in across cap 68 secured to the block 59. Each worm 1s connected with an operating thumb Wheel 69 rejecting -u wardly above the cap 68. y' turning tl i thumb wheel in'one direction or the other the tensioner is correspondingly adjusted or rotated for longer or shorter pitch of coil.

As the Wires are coiled by two companion coilers, the same are passed rearwardly of the machine to the cut oli device comprising first a strand-unitin guide 70 similar to a coiler and by which 1; 1e two com anion wires I are brought together and .there'a ter run as a single strand-,and second, a cut oil" proper com rising a knife block 71' and a knife 72 whic i is secured uponItlie reciprocating eut ter bar 73, Figs. 5, 18, 20 and 21; e

As seen in Figs. 18, 2.0 and 21, the cylinder ever the cutter bar is reciprocated in the,

proper direction. The series of cut offs are secured in suitable manner to across bar Y4, which is adjustable longitudinally of the machine towards and away from the coilers in a manner and for a purpose herein ex .lained.

In order to reciprocate the cutter ar and thereby cause the'knife to operate at the proper predetermined time, I provide suita transversely sliding able operating connections comprising, in the present instance, an operating lever which is pivoted at its upper end to a block 76 secured to the cross bar 74, F lg. 16. This lever is connected at a point intermediate its length with the cutter bar by means of a transverse pin '77 and the lower end of such operating lever is operatively connected with plate 78, Figs. l9 and 21, This plate is providedwith an actuating pin 79 arranged to enter the angular opening formed in the slot of the operating lever 75. The obje t of the slot and in connection between the sliding plate anc the lever 75 is to *erinit the trigger mechanism hereinafter re 'erred to, to be operated in advance of the cutter bar, it being understood that the lever 75 cannot be o erated until after the pin 79 has traversed t e length of the slot and contacted the oppositeend thereof, so that the cutter bar is moved only .near the last moveinent of the sliding plate.

The, slidin frame is supported and arranged to sit e in a frame 80 hereinafter referred to as the trigger frame which is itself supported within a housing 81. Thishousmg supported by arid forms a part of the oscillating head, but is adjustable in relation therewith; By preference, and as indicated in Figs. 5 and 21, the sliding plate 78 is dovetailed. into the trigger frame 80. In order to reciprocate the sliding plate, I provide'the same on one side with a block 82, having a suitable opening to receive theiupwardly extending .121 or bolt 83 extending upwardly from a bllick 84v arranged to reciprocate upon a slide 85 on the lower cross piece'of the housing 81, Figs. 16, and 19, 20 and 21-, This sliding block is connected by means of an op erating link 86 with the ower or driving mechanism, as hereinafter t escribed.

To roperly position the wire (or rather pair of double wire fabric) after the same has been cut olf, in order that the next succeeding wire which is to herun as a cord may not be inter fered with in the running thereof, 1 provide suitable mechanism located rearwardly of wires forming the double strand in a ;tially behind the finger 87 an and associated with each cut 05 mechanism, to the end that when the cords are bein run,- the coil or wire already run may be rawn forwardly to 'a slight extent, after ,being cut off. As shown in Figs. 18, 20' and 21., such positioning mechanism comprises a finger 87 arranged to have an irregular movement adj acent to and below the coil as it is run, such movement being downwardly below the coil, rearwardly, upwardly and thence forwardly in contact with the coil, such path of movement being diagrammatically illustrated in Fig. 23. This finger or trigger 87 formsthe upper extension of an arm, 88 pivoted at its lower end to a rocking lever 89. This lever is secured to a transverse rock shaft 90 which is provided near one end with a pro'ectin'g actuating arm 91, whose extreme en is up eratively connected with a lever .92. lever is pivoted to the forward side of the slide 78. In order to rock the lever 92, the

This

other end thereof is provided, as'seen 1n Figs. I

19 and 22, with a stud 93 adapted to travel in a cam slot 94 formed in a block 95 which is secured to and substantially closes an an ular opening in the slide 78. As this slide moves; it first causes the arm 91 to move u wardly, dueto the descent of the stud 93 in the deseendi 1g, portion of the cam-Way 94,' after which the stud rises to the top of the cam-way, duet-o the tension of the spring96, which has been resisting said movement of' the arm 91 and consequently of the rock shaft 90. The stud 93 then moves laterally with respect to the cam-way and trips the spring pressed pawl 97 downwardly, which finger springs upwardly again in normal position after being cleared by the stud 93. The result of this movement of the stud is to partially rock the shaft 90 and thereby raise and lower the finger 87. geris subject to another movement due toits connection with a rock shaft 98, to which is connected, through the medium of the link 99, a crank arm 100 secured tosuch rock shaft. This rock shaft is provided witha forwardly extending actuating arm lOlwhose extreme free end extends into and is actuated by a cam slot 102 formed in the slide. The shape of this cam slot is such that the arm 101 is moved up and down as the slide reciprocates, so that, through the medium of the connections described the trigger 87 is given a rearward and forward movement, the result of the movements being. substantially as illustrated in Fig. 23. The rock shaft 98 is held innormal position bythe pressure of the coiled spring 103, which'serve's to take up the lost motion. I

Associated with each trigger mechanism a retaining finger 104 arran ed'substanadapted to retain the coil rearwardly thereof in its normal position at the time when the finger or I trigger 87 is operating to displace the same,

However, the trigwardly it will cause the coil which has been previously runand cut oif, to be moved and old against the coil just run in to serve as the cord. 1 l

Inorder to accommodate changes in the pitch of the wife for weaving wire fabrics of different pitch, it, becomes necessary to provide adjustments of the trigger 87 finger 104 and the out off mechanism, such adjustments of each other so that the parts just referred to may be adjusted relatively to each other. 111 the present instance, these parts are made ad ustable as being independent follows.

The forward end of the bolt 107 "is screwthreaded and surrounded at this point by a worm gear 109 bearing within the bracket and meshing with ,a worm 110 mounted in the same bracket. Each end of the-cut oli' mechanism is provided with the adjusting mechanism described and to transmit the movement from one side to the other 10 is extended transversely of the machine and provided at such other side thereof with the similar, worm operating similar mechanism for adjusting both ends of the cutter bar in unison.

This master gear is arranged at the inner end of a shaft 1220, Figs. 16 and 20, which is journaled in the bracket 108 and extends extraneous of the machine, where its outer end may be provided with an operating handle 121. When the handle is turned in one direction or the other, either the cut off mechanism or the trigger mechanism is operated according to which pinion 117 or 118 is .at that time in engagement with the master gear.

Each of the series of three fingers 104. is similarly mounted and the shaft 125, on which the worms 124 are formed, extends transversely of the machine, the'same being provided at a suitable point with a milled hand wheel 126, for the purpose of manually rotating such shaft and consequently the worms v 124. .By rotating the the fingers shaft in one direction or the other, 104 are moved forwardly or backwardly as the case may be.

For the purpose of raising and lowering the trigger frame within its housing, I provide a rock shaft 12-7 journaled in the hous-- ing, as seen in Figs. 20 and 31, and provided at its ends with similar parallel operating arms 128, which are slotted to receive the studs 129, projecting laterally from the opposite sides of the trigger frame and projecting through vertical slots in the side walls of the housing. The operating arm 128 on one side is extended and the same is operatively connet-ted with the power mechanism for automatic operation, as hereinafter described.

The wires as coiled are delivered to the weaving devices by which successive coils or strands are woven or interlocked in order to form a complete coiled wire fabric. Each pair of coilers is provided with one of the weaving mechanisms, there being in the present instance three of them, similar in construction and operation. Each weaving mechanism comprises essentially a weaving channel formed by stationary and movable bars in association with movable members working partially over the weaving channel from opposite sides thereof and serving to engage and eject the fabric as it is being formed. A Referring to the present construction as;

more particularly illustrated in Figs. 3, 4 and formed at its, upper end with a thickened .Ilange and recessed at its upper innerside or 130 vided with a series of upwardly projecting ,143 in the ejecting shutter. l is arranged to form a continuation of one of blocks 150 in the channel.

Referrin first to the bar 132, the same is substantial y the samelength as its-strip or plate 130-and provided with a series of upwardly extending pins 134, j which are received by obliqueslots 135 in a plate 136, transversely movablehupon the top surface of the plate 130 and hereinafter designated the'retaining shutter. In order to hold this shutter in place upon its plate or I strip 130, I provide screws 13? passing I through transverse slots in the shutter and screwing into the plate 130. In like manner, the actuating bar 133 is adapted to slide longitudinally in its plate 131 and is pro- 139, movable transversely upon. the top sdr-. face of the plate 131 and hereinafter designated the ejecting shutter. This shutter is arranged to slide beneath a plate 140 which is held in place and secured to the plate 131 by means of the screws 141, passing through the plate 140 and screwing into studs 142, which are accommodated bytr'ansverse-slots This plate 140 pins 138 received by oblique slots in a plate j the walls of the channel and to this end such plate is provided adjacent the channel with a flange 144, projecting upwardly and also downwardly to substantially meet the lower rojecting lip 145 of the ejecting shutter. he actuating bar 1.33 is operated in substantially the same way as the bar 132, as hereinafter described.

Inasmuch as I have provided electrical means for holding and clamping the wire last run in the channel, I arrange a plate or strip l46of brass or other non-magnetic material on the inner face of the stationary plate 130 and likewise I provide a similar plate 147 on the inner side or face of the movable plate or strip 131. During the ejecting operation the l fabric is raised bodily upwards by the upward movement of the side plate 131 and the parts attached thereto, including the ejecting shutter 139. By preference, line the platen 146 with an easily removable wear plate 148 l which receives the wear or friction of the Wire coils and which may be readily replaced, I when desired, by a new plate. l The electrical device for clamping the coil l last run in the channel comprises an. elojnl gated electro magnet 145 which is'of a size to lit within the weaving channel in such a manner that its magnetic poles form the bottomof the channel and are supported on I As shown, there 1 blocks l of the weaving channel and the same are received in vertical recesses in the plate. 14?, forming one of the walls of the channel. The plates l is a'se'ries of these magnet supporting and other parts forming the weaving channel are held in place by a series of yokes 151 arranged at intervals along the length of the weaving channel. members or platesl30 and 146 are secured to said yokeby ascrew 1-52,. while the magnet supporting blocks are secured thereto by screws 153. 1 v

As shown in Figs. 29. to 32, I interpose between oneof the upright walls of the yoke and the outer surface of the movable plate 131 a thin strip or fillet 156, which is removable, as hereinafter explained, for the purpose of widening the weaving channel in order to provide for the weaving of fabric with a larger diameter of coil. It will be understood that the electro magnet is con-' nected with a circuit breaker automatically operated, as hereinafter described, whereby the magnet may be energized and dener- As shown, the stationary gized at the proper time in the cycle of opera--.

tion of the machine.

. In explaining the mode of operation of the weaving devices, it will be assumed, that the fabric has already been started or developed to the extent of three coils, as seen in Figs. 29, 30 and 31, such coils being marked a, b

and c, and that a fourth coil marked 6. has f just been run. into the channel and has been interwoven with the previously run coil marked c. At this time the electro magnet is energized, Fig. 29, with the result that the coil d is held firmly along its entire length to the bottom of the channel and the ejecting shutter 139 has'its lip 145 in engaging posi-- tion in the intersection between :the coils I) and c, inasmuch as the ejecting shutter is at this time projected inwardly and partiallyv across the channel. The retaining shutter 136 is now in its idle or outward position, free of the weaving channel, so as not to in terfere with the completed fabric as it is being ejected. the channel is at this time in its intermediate position ready to rise and thereby eject the fabric. When the shutter has risen to itsupward limit of movement, as seen in Fig.- 30, the lower helix of the coil 0 is adjacent the upper helix of the coil 05, itbeing understood that the ma net is ener ized durin the e"ect- I h h D gage in the intersection between the coils b v and 0, so as to retain the fabric in proper position-in the channel and prevent its escape therefrom. Just as the retaining shutter takes its engaging position, as shown. in Fig. 30, the ejecting shutter is retracted clear of the weaving channel and. this movement is Moreover, the movable side of 1
